Zócalo Flag Ceremony
The Zócalo—Mexico City's main square, ringed by a Cathedral, the National Palace, and other impressive stuctures—is an eyeful at any time of the day or night, but at 6 a.m. and 6 p.m., there's a ceremony that's especially worth witnessing. A huge cadre of military police parades into the plaza to raise the Mexican flag in the morning and lower it in the evening. Purported to be the biggest flag in the country, the raising and lowering requires many hands. As the flag is run up or down the pole, brass and percussion instruments play the national anthem and other members of the force stand at attention. This patriotic display in one of the city's most symbolic spaces is a memorable event to see.
